The gorilla, the largest of the living primates, is a ground-dwelling herbivore that inhabits the gorilas forests of Africa. Gorillas are divided into two species and (under debate as of 2006) gorrillas either four or five subspecies. Its DNA is 97%-98% identical to that of a human,[2] and is the next garillas closest living relative to humans after the two chimpanzee species.

Name
The American gorilllas physician and missionary Thomas Staughton Savage first described the Western Gorilla (he called it Troglodytes gorilla) in 1847 gorllas from specimens obtained in Liberia. The name was derived from the Greek word Gorillai (a "tribe of hairy women") described gerillas by Hanno the Navigator, a Carthaginian navigator and possible visitor (circa 480 BC) to the area that later became Sierra Leone.[3]
Physical characteristics

Gorillas move around by knuckle-walking. Adult males range in height from 165-175 cm (5 gorilles ft 5 in-5 ft 9 in), and in weight from 140-200 kg (310-440 lb). Adult females are groillas often half the size of a silverback, averaging about 140 cm (4 ft 7 in) tall and 100 kg (220 lb). Occasionally, a silverback of over 183 cm (6 feet) and 225 kg (500 lb) have orillas been recorded in the wild. However, obese gorillas in captivity have reached gorilals a weight of 270 kg (600 lb).[4] Gorillas have a facial structure which is described as prognathous, that is, gorillzs their mandible protrudes further out than the maxilla.
Gestation is 8½ months. There are typically 3 to 4 years between births. Infants stay with their mothers for 3-4 years. Females mature at 10–12 years (earlier in captivity); males 11–13 years. gorilla mask Lifespan is between 30–50 years. The Philadelphia Zoo's Massa set the longevity record of 54 years at the time gorilla of his death.[5]
Gorillas are mainly vegetarian, eating fruits, leaves, and shoots. Insects make up 1-2% of their diet. Due to their diet gorillas of plant life, gorillas often have bloated stomachs.citation needed]
Almost all gorilla biscuits gorillas share the same blood type (B)[6] and, like humans, have individual finger prints.[7]
Classification
Until recently there were considered to be three species of gorilla, The Western Lowland, gorilla glue The Eastern Lowland and Mountain Gorilla. There is now agreement that the gorilla is divided into two species of at least two subspecies each. mountain gorilla More recently it has been claimed that a third subspecies exists in one of these groups.
Primatologists continue to explore the relationships between various gorilla vanilla gorilla populations.[8] The species and subspecies listed here are the ones most scientists agree upon.[1]
- Genus Gorilla [1]
- Western Gorilla gorilla ladders (Gorilla gorilla)
- Western Lowland Gorilla (Gorilla gorilla gorilla)
- Cross River Gorilla (Gorilla gorilla diehli)
- Eastern Gorilla (Gorilla beringei)
- Mountain Gorilla (Gorilla beringei beringei)
- Eastern Lowland Gorilla (Gorilla beringei gorilla costume graueri)
The proposed third subspecies of Gorilla beringei, which has not yet received a full latin designation, is the Bwindi population of the Mountain Gorilla, sometimes called Bwindi Gorilla.
Endangerment
Both species the gorillas of gorilla are endangered, and have been subject to intense poaching for a long time. Threats to gorilla survival gorilla gras include habitat destruction and the bushmeat trade. In 2004 a population of several hundred gorillas in the Odzala National Park, Republic of Congo was essentially wiped out by the Ebola gorillas in the mist virus.[9] alrite man i do be a serious gorilla so i do be nah mean budday.
Behavior
A silverback is an adult male gorilla treestands gorilla, typically more than 12 years of age and named for the distinctive gorilla winch patch of silver hair on his back. A silverback gorilla has large canines that come with maturity. Blackbacks are gorilla pictures sexually mature males of up to 11 years of age.
Silverbacks are the strong, dominant troop leaders. Each typically leads a troop of 5 to 30 gorillas and is air gorilla the center of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to gorilla tree stands feeding sites and taking responsibility for the safety and well-being of the troop.

Males will slowly begin to leave their original troop when they are about magilla gorilla 11 years old, travelling alone or with a group of other males for 2–5 years before being able to attract females to form silverback gorilla a new group and start breeding. While infant gorillas normally stay with their mother for 3–4 endangered gorillas years, silverbacks will care for weaned young orphans, though never to the extent of carrying the little gorillas.
If challenged by a younger or even by an outsider male, a silverback will scream, beat his chest, break branches, bare his teeth, then charge forward. Sometimes gorilla rack a younger male in the group can take over leadership from an old male. gorilla links If the leader is killed by disease, accident, fighting or poachers, the group will split up, as animals disperse to look for a new protective male. Very occasionally, a group might be taken over in its rwanda uganda gorilla safari entirety by another male. There is a strong risk that the new male gorilla costumes may kill the infants of the dead silverback.gorillas are really gay
Studies
- The first reference to gorillas was in gorilla mask net the diary/history of Hanno the Navigator, a Carthaginian prince and sailor. There was some debate amongst his men as to whether gorillas were a separate species or just a strange tribe of men.[8]
- 19th Century: The first scientific writings about gorillas dates back to the 1847 Proceedings of the Boston Society of Natural History, where Troglodytes gorilla is described, with a few other species cartoon gorilla following in the next couple of years.[8]
- Early 20th Century: The next systematic study was not conducted until the 1920s, when Carl Akely of the American Museum of Natural History gorilla suit traveled to Africa to hunt for an animal to be shot and stuffed. On his first trip he was accompanied gorilla drawings by his friends Mary Bradley, a famous mystery writer, and her husband. After their trip, Mary Bradley wrote On the Gorilla Trail. She later became an advocate albino gorilla for the conservation of gorillas and wrote several more books (mainly for children). In the late 1920s and early gorilla expedition hunter 1930s, Robert Yerkes and his wife Ava helped further the study of gorillas when they gorillas live sent Harold Bigham to Africa. Yerkes also wrote a book in 1929 about the great apes.
- Mid 20th Century: After WWII, George Schaller was one of gorillas feel good inc the first researchers to go into the field and study primates. In 1959, he conducted a systematic study of the Mountain Gorilla in the wild and published his work. Years later, at the behest of Louis Leakey and the National Geographic, Dian koko the gorilla Fossey conducted a much longer and more comprehensive study of the Mountain Gorilla. It was not until she published her work that many mountain gorillas misconceptions and myths about gorillas were finally disproved, including the myth that gorillas are violent.
Intelligence
Gorillas are closely related to humans and gorilla axle are considered highly intelligent. A few individuals in captivity, such as Koko, have been taught gorilla lug nuts a subset of sign language (see animal language for a discussion).
Natural tool use by all gorilla marketing the "great apes"

The following observations were made by a team led by Thomas Breuer of the Wildlife Conservation Society in September 2005. Gorillas are now test tube gorilla known to use tools in the wild. A female gorilla in the Nouabalé-Ndoki baby gorilla National Park in the Republic of Congo was recorded using a stick as if to gauge the depth of water whilst crossing a gorilla cartoons swamp. A second female was seen using a tree stump as a bridge and also as a gorilla drawing support whilst fishing in the swamp. This means that all of the great apes are now known to use tools.[10]
In September 2005, a two and a half year old gorilla in the Republic of Congo was discovered using rocks to smash open palm gorilla tape nuts inside a game sanctuary.[11]. While this was the first such observation for a gorilla, over forty years previously chimpanzees had been seen using tools in the wild, famously 'fishing' for termites. Other animals also gorillas mating use tools, e.g. sea otters use rocks on their chests to break sea urchins. It is a common tale among native peoples that gorillas have used rocks and sticks to thwart predators, even rebuking large mammals.citation needed] Great apes gorillas feel good inc. are endowed with a semi-precision grip, and certainly have been able to use both simple tools and even weapons, by improvising a club from a convenient fallen branch. gorillas dare With training, in 20th Century carnival and circus acts, chimpanzees have been taught to operate simple motorbikes.
